The Luleå cathedral was built after the great fire in Luleå in 1887. The fire completely destroyed the old church on the site, Gustaf's church, which was from the late 1700s. Designed by architect Adolf Emil Melander in a neo-Gothic style, the new cathedral was initially named Oscar Fredrik's church upon its 1893 opening, in honour of King Oscar II. Spanning 54 metres in length and 35 metres in width, the cross-shaped cathedral features a towering spire exceeding 60 metres in height. Architect Knut Nordenskjöld led a redesign that veered towards modernity, stripping away wall paintings and star decorations, leaving a pristine white interior. Despite these changes, echoes of the original style linger in the church entrances, creating a harmonious blend of historical and contemporary aesthetics.
